VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 347,712, dated August17, 1886.

Application filed May 4, 1885. Serial No. 164,271. (No model.)

To all whom it may concern.-

Be it. known that I, MARTIN L. HULL, of

Cleveland, in thecounty of Guyahoga and Slate of Ohio, have inventedcertain new and useful Improvements in Vapor-Burners; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in thcart to which itpertains to make and use the same.

My invention is an improvement in vaporburners; and it consists, first,in the combination of a vapor-tube, a horizontal arm extending therefromprovided with a jet-orifice, a valve-casing having a chamber in which islocated the primary needle-valve having a transverse recess, ahorizontalsleeve connected to the valve-casing, a front plate having a socket, avalve-rod secured in the casingsleeve and plate'socket, an eccentriclocated on the inner end of the valve-rod and occupying the recess inthe primary needle-valve,

and a crank at the outer end of the valve-rod provided with a handle, ashereinafter described; second, in the combination, with a primaryneedle-valve and its casing, of a Va por-tube having a small orifice,and an extension to the tube beneath the orifice, an initial heating-cupsupported under the vapor-tube, a secondary valve controlling theorifice, and a lever having limited movement in a horizontal plane foroperating the secondary valve, as hereinafter described; third, in thecombination of a vapor-tube having a small orifice in the side thereofand an extension thereunder, an initial heating-cup havinga suitablesupport, a deflector secured opposite to the orifice, forming a chamberfor directing the flame upward, provided with an extension in thedirection of the cup, a secondary valve controlling the orifice, and ahorizontal lever for operating the secondary valve, as hereinafterdescribed.

In order that my invention may be fully understood, I will proceed todescribe it with reference to the accompanying drawings, in which-Figure 1 is an elevation of a front plate for application to the face ofa vapor-stove, showing the handle in open position. Fig. 2 is a verticalsection on the line y y, Fig. 1. Fig. 3 is a side elevation of myimproved burner, the front plate being omitted. Fig. 4 is an enlargedvertical section through the center of the burner, showing thearrangement of the several parts. 5 is a front view of the primaryneedle-valve detached, showing the recess for the reception of theeccentric. Fig.

the small flame upward for heating the main chamber. Fig. 7 is ahorizontal section of the deflector, vapor tube extension, and secondaryvalve on the line a; w, Fig.4. Fig. 8 is a plan View of the horizontallever by which the secondary valve is operated.

A is a plate of metal for attachment to the front of the frame of avapor-stove. ,This plate is formed with acurved slot or opening, A, forthe shank B of a handle, 13, and a socket, A for the support of theouter end of the primary valve-rod. On the left and right of the slot oropening, respectively, are the words open and shut.

The burner is constructed with a platform, J, having a; main chamber, J,which receives the supply-pipe K.

J is a vapor-tube extending from the platform, having a horizontal arm,K. This arm is provided with a jet-orifice, r, in an adjustable nipple,R, and with a screw-plug, K closing the outer end thereof.

Extending'from the horizontal arm K is a casing, J in whose chamber J islocated the primary valve F, projecting across the arm K for controllingthe jet-orifice, and formed with a transverse recess, F.

Projecting from the valve-casing is a horizontal sleeve, J, whichreceives the primary valve-rod D. This valve-rod is provided at itsinner end with an eccentric, E, which occupies the recess F in theprimary valve. The outer end of the valve-rod is provided with a crank,C, and is supported in the socket A of the plate.

To the crank O is secured the handle B.

M is the initial heating-cup secured to the lower end of thevalve-casing.

The vapor-tube J is formed with a small orifice, N, in one side thereof,and also with an extension, J in which is fitted a secondary valve, G,for controlling said orifice.

To the secondary valve is secured adjust ably (by means of a set-screw,H,) a hand-1ever, H, by which it is operated. The leveris formed with ahorn, H", which abuts against 6 is a front view of the deflector fordirectingfor directing any fluid which may escape through the smalloriiico into the cup.

P is the burner proper, secured by a pipe, 0, to the platform. The crankOis adjustably connected to the valve-rod D by means of a.

set-screw, C.

The operation of the burner is very simple. hen it is desired to light aflame, the lever II is turned, so as to allow a small quantity of fluidto pass from the orifice N into the cup M, where a match is applied tothe fluid to ignite the latter and heat the burner. As soon as the gasbegins to flow, the handle Bis turned to the left, causing the valve-rodto open the primary valve by means of its eccentric, and the gasimmediately streams up past the necdle -point through the jet orifice,and up through the pipe 0, (\vhere'it is mixed with air,) into thechamber of the burner proper, I, where it may be lighted and utilized inany, way desired. By means of the orificeNa small flame is maintainedfor keeping the vaportnbe and main chamber hot while the primary valveis closed, The flame also heats the portion of the supply-pipecontiguous to it and to the main chamber. Initial heating is thereforeonly required when the flame is first started. \Vith the limitedmovement permitted to the lever 1[ there is no liability of thesecondary valve being opened too far. The val verod is firmly supportedin the plate-socket,and the crank-handle gives positive movement to therod.

Having thus described my invention, the following is what I claim as newtherein, and desire to secure by Letters Patent:

1. The combination of a vapor-tube, horizontal arm K, having ajet-orifice, valve-casing J", having chamber-J, horizontal sleeve J,primary needle valve F, occupying the chamber, having a recess, I frontplate, A, having a socket, A and a valve-rod, D, socured in thecasing-sleeve and plate-socket, provided with eccentric E at its innerend, occupying the recess in the needle-valve, and having a crank, G,and handle B at its outer end, substantially as described.

2. The eombination,with a primary needlevalve and its casing, of avapor-tube, J, having a small orifice, N, and an extension, J, initiallieatingcup supported thereunder, a secondary valve. G, controlling theorifice, and a lever having limited movement in a horizontal plane, foroperating the secondary valve, substantially as described.

3. The combination of a vapor-tube, J, having a small orifice, N, in theside thereof, and an extension, J, initial heating-cup supportedthereunder, deflector L, secured opposite to the orifice, forming achamber, L", for directing the flame upward, and having an extension, L,in the direction of the cup, a secondary valve, Cr, controlling theorifice, and a horizontal lever for operating the secondary valve,substantially as described.

In testimony whereof I sign this specification, in the presence of twowitnesses, this 1st day of Hay, 1885.
